"Our AC went out in the middle of summer and I called to schedule an appointment and they made it out the same day! They were very professional and completed the necessary maintenance extremely quickly. We had air again by the end of the day. It’s also one of the most affordable places we’ve ever used for our heating and air maintenance and repairs."

"I can't recommend Jade Heat and Air more. I struggled for years with a recurrent problem with my HVAC and dealt with several other service providers who couldn't seem to fix it. Jade fixed it and it stayed fixed for three years. Just had them out to fix a new problem and couldn't be happier with Cesar Aguilar."

"Mr. Le was exceptionally good in responding to my call and came within 30min of calling him and installed a brand new heat pump / air conditioner the very next day. The pricing was reasonable and his work was immaculate. He is a very thorough professional and very nice to work with. He is very detail oriented and expects everybody to adhere to his standards and doesn't cut comers. His people were very good and cleaned up my whole work place and left with no trace of any dirt. Highly recommend them."
Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
